Something I hadn't considered until now is how brutal the mission to kill Jarvia and most of the Carta in Orzammar is for Brosca. I'll never forget the emotional gut punch that was having to fight and kill Leske, who is probably only true friend Brosca has ever had in all their life (I remember desperately searching if there was a dialogue option or something to let him live but there is none), but I also just thought that Brosca must have known most, if not all of those Carta members that we fight through the mission.
And knowing how the casteless are pretty much cut off from the rest of Orzammar's society and most are forced into a life of crime, Brosca must have known and possibly have been friends or at least care for for a lot of the Carta members, and also possibly have worked with them often under orders from Beraht and Jarvia.
Then after becoming a Warden, returning to Orzammar and under orders from either Harrowmont or Bhlen, they have to go to their old home in Dust Town and kill Jarvia (who was alledgely planning to use her growing power in Orzammar to force the Assembly to recognize the rights of the casteless), Leske and pretty much everyone else they knew during their many years growing up and while being a part of the Carta.
Just another bit of tragedy for Brosca's story.
